DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT OF THE INVENTION

(6) In view of the provided drawings, it can be observed how in a preferred embodiment of the invention, the container bag 1 for containing semen for artificial insemination of animals presented herein, of the types which are formed by at least two sealed sheets 2.1, 2.2, of thermoplastic material, forming a tubular body 3 with an inner hollow 4 perimetrically closed except at at least one of its ends 4.1 and this inner hollow 4 being divided by means of a central constriction 5 into a first contiguous enclosure 7.1 and a second contiguous enclosure 7.2 which are communicated by means of a cannula 6 secured to said constriction 5, comprises a closure plug 10 for closing said cannula 6 secured to the bottom 13 of the second enclosure 7.2 of the inner hollow 4 and means for securing said closure plug 10 to the bottom 13 of said second enclosure 7.2.

(7) This bag in turn comprises means for securing the cannula 6 to the central constriction 5.

(8) In this preferred embodiment of the invention, as shown in FIG. 4, the cannula 6 comprises a tube 8 which has a flattened head 9 at a first end 8.1. Likewise, the means for securing the cannula 6 to the constriction 5 are formed by welding the head 9 to said constriction 5.

(9) As a result of the flattened head 9 of the cannula 6, the section of which is considerably smaller at the ends, a perfect welding to the constriction 5 is favored, whereby the proper securing and leak-tightness thereof is assured.

(10) As can be observed in FIGS. 1 and 2, the closure plug 10 of this container bag comprises a flexible longitudinal body 11 that can be tightly fitted into the cannula 6 and a head 12 outside same where said closure plug 10 is secured to the bottom of the second enclosure 7.2.

(11) The container bag 1 for containing semen in turn comprises means for securing the closure plug 10 to the bottom 13 of the second enclosure 7.2, which in this preferred embodiment of the invention are formed by welding part 12.1 of the head 12 of the closure plug 10 to the bottom 13 of said second enclosure 7.2.

(12) Said second enclosure 7.2 is sized such that it favors connecting the insemination catheter and the outlet cannula in an easy and loose-fitting manner.

(13) On the other hand, the bag 1 in turn comprises means for opening it through a section of the second enclosure 7.2, which in this preferred embodiment of the invention are formed by a pre-cut line 15 along said section and a hole 16 limiting same.

(14) In turn, the cannula 6 secured to the constriction 5 is of a length such that the second end 8.2 of the tube 8 forming the cannula protrudes from the pre-cut line 15 existing in the section of the second enclosure 7.2.

(15) As shown in FIG. 3, this bag 1 is presented in series where each one of the bags 1 is attached to the two adjacent bags by means of pre-cut lines 17 separating heat-sealing areas 14 of contiguous bags.

(16) The drawbacks existing in the state of the art are successfully solved with the container bag for containing semen for artificial insemination of animals presented herein.

(17) Therefore, as a result of a closure plug for closing the cannula secured to the lower part of the bag, specifically to the base of the second enclosure of the inner hollow, said plug does not come loose and fall after opening the bag.

(18) Hence, it does not come into contact with external agents and therefore continues to be in perfect conditions to be reused and to again close the bag with it, which bag is thus protected against possible spillage or the entry of hazardous elements therein and being kept in perfect conditions to apply new doses of insemination.

(19) Furthermore, the shape of the closure plug assures that no stagnant semen residues remain inside the cannula, preventing the formation of a barrier of dead spermatozoids, whereby higher process effectiveness is achieved for applying the subsequent doses of semen.

(20) Likewise, soil contamination is prevented because since the plug does not fall onto the liquid manure, when the liquid manure is collected to be reused as fertilizer, said plugs are not included therein, the contamination of the soil where said liquid manure is disposed of thus being prevented.

(21) On the other hand, a perfect fixing of the cannula to the constriction of the bag is obtained, assuring that the cannula does not move with respect to said bag and that the cannula does not sink into the bag due to the pressure of connecting the insemination catheter. This is obtained as a result of the shape of the head of the cannula favoring a perfect welding of same to said constriction.

(22) Likewise, as a result of the length of the cannula causing the second end of the tube forming it to protrude from the pre-cut line of the second enclosure, when the bag is opened, the cannula protrudes from the cut made and the conditions for connecting said cannula and the insemination catheter are thereby improved.

(23) Furthermore, the sealing of the cannula and of the plug, respectively, creates leak-tightness and favors keeping the sanitary cleanliness of both elements, this being very favorable for the insemination process.
